Serial No."405,71e-.- f l7 The present invention relates to a 'recep- 'tacle for packing ampules;more particularly it relates to a receptacle for packingsuch am p ulesas are described, for instance, inU. S. Q

atents 1,699,305 and 1,713,854 of Felix Meyer. The said ampules arecharacterized by possessing at a certain place of their neck a localpermanent tension of 'suchform,

course and intensity that this tension will not 7 sufiice to crack theglass at once or at an unintentional time, for instance, at a suddenchange of temperature, bu t only when this crack is intentionally andwilfully caused by. slightlyinjuring the skin '-0I surface of the J5glass at'any point of'the part where the tension has been set up(compare-page-l of U; S. Patent 1,713,854).

The object of my invention is'tofprovide the receptacle in which theampules are tobe packed, with a device capable of causing the crackingof the glass at'the part where the tension has been set up, thusobviating the use of a special device for performingthis feature. Oneway to accomplish this aim is to provide the box in which the ampulesare to be packed, with a hole, the circumference of V, the edge of theout being likewise provided with a layer ofcarborundum or a similarmaterial, fixed to the cardboard" by means of water glass or a similaradhesive material. f

The accompanying drawings give an il-.

fmy inventionconsisting mainly in the combi- 113M011 of the device forcausing the breaking of the neck of the ampule with the packing box,thus obviating the use of two separatedevices. packing ampules in theway as shown in my drawings are known to the art. Furthermore, v

of ampules by means of carborundum or other it is known to scratch thesurface of theneck similar materials. I do not claim these features'separately, buthave limited my claims 1. A receptacle forv packing-such'ampulesli-s as possess at a certain place a local permanent tensionbeing sufiicient to crack the glass by slightly injuring its surface,the said receptacle being providedwith a hole in at' least one of itssides, the circumferencev of the said hole being provided with a layerof a material being as hardor harder than glass I c and the diameter ofthe hole being so that that part of the'ampule which possesses the local109 I' recognize that receptacles for c, i

permanent tension comes into contact with the abrasive substance appliedto the periphery of the hole.

2. A receptacle for packing such ampules as possess at a certain place alocal perma' nent tension being suficient to crack the glass by slightlyinjuring its surface, the said receptacle being provided with a holeinat least one of its sides, the circumference of the said hole beingcovered with carborundum', and the hole being of such size as to receiveand scratch that part of the alnpule which possesses the local permanenttension.

3. A receptacle for packing ampules, the said receptacle having anaperture the edges of which are provided with an abrasive material ashard as or harder than glass render- 7 ring possible the injuring of theampule at that part which is capable of cracking by the said injuring,the said aperture being of such size as to receive and scratch the partof the ampule to be cracked.

In testimony whereof, I afiix my si nature.
